Abstract: | |
The Casimir energy for massless scalar field which satisfies
priodic boundary conditions in two-dimensional domain wall
background is calculated by making use of general properties of
renormalized stress-tensor. The line element of domain wall is
time dependent, the trace anomaly which is the nonvanishing
Tμμ for a conformally invariant field after
renormalization, represent the back reaction of the dynamical
Casimir effect.
